feasibility bfrt geriatric stroke patients

Conditions: Stroke

Summary: the focus of this interventional study is to assess the feasibility of blood flow restriction training (bfrt) in a geriatric stroke population. patients will undergo a 4-week program of bfrt additionally to our standard physiotherapy, conducted twice weekly by experienced physiotherapists. the main goal of the study is to assess its feasibility concerning the safety and tolerance of bfrt from a patients and therapists scope. furthermore, the investigators want to establish the proportion of eligible individuals \& their willingness to undergo bfrt, as well as the time investment. the feasibility of an effectiveness study and potential sample size will be evaluated aside.

stroke is often linked to a loss in muscle strength and a decline in functioning during daily life. in the past, several studies have focused on the effects of resistance training on muscle strength in order to restore patients functioning in daily life. for optimal improvements in muscle strength, the use of high loads with few repetitions per set have been recommended, even within the geriatric population. however, the use of high load exercises in a geriatric population can often be challenging, particularly in patients who have suffered a stroke. to counter this, blood flow restriction training (bfrt) might give some opportunities. bfrt is a relatively new technique for strength training using a cuff to compromise blood flow in combination with low loads. it is a japanese technique from origin also known as kaatsu and has been proven to be effective in several populations, including a geriatric population. during this study, patients will undergo 8 sessions of bfrt given by experienced physiotherapists, twice a week during a 4-week program additionally to standard physiotherapy program: the geriatric activation program pellenberg (gapp). each patient will undergo 1 or 2 specific predetermined exercises for the upper or lower limb, based on the individual goals. the main goal of the study is to assess its feasibility concerning the safety and tolerance of bfrt from a patients and therapists scope. furthermore, the investigators want to establish the proportion of eligible individuals \& their willingness to undergo bfrt, as well as the time investment. the feasibility of an effectiveness study and potential sample size will be evaluated aside.
